Another pipeline operator sends the disabled job triggers to the Format-Table cmdlet, which displays the selected properties of the job triggers in a table. The properties include a new JobName property that displays the name of the scheduled job in the JobDefinition property of the job trigger.

PS C:\> Get-ScheduledJob | Get-JobTrigger | where {!$_.Enabled} | Format-Table Id, Frequency, At, DaysOfWeek, Enabled, @{Label="JobName";Expression={$_.JobDefinition.Name}}
